John will need to paint 347 square feet of wall in his rectangular basement after subtracting the area of the door that will not be painted.
John will paint the four walls of his rectangular basement. To calculate how many square feet of wall he will need to paint, we must first determine the total area of the walls and then subtract the area of the door.
The total wall area is calculated as follows:
Two walls are 10 feet long and 8 feet high, giving 2 x (10 x 8) = 160 square feet.
The other two walls are 13 feet wide and 8 feet high, giving 2 x (13 x 8) = 208 square feet.
So, the total wall area is 160 + 208 = 368 square feet.
The door measures 3 feet by 7 feet, which equals 21 square feet.
To find the area John will paint, we subtract the area of the door from the total wall area:
368 square feet - 21 square feet = 347 square feet
Therefore, John will need to paint 347 square feet of wall.

Step-by-step explanation:
The two sides of the triangle that are by the right angle are called the legs... and the side opposite of the right angle is called the hypotenuse
Identify the triangle that contains an acute angle for which the sine and cosine ratios are equal.
Triangle A B C has angle measures 50 degrees, 40 degrees, and 90 degrees.
Triangle A B C has angle measures 45 degrees, 45 degrees, 90 degrees. The lengths of sides A C and C B are congruent.
Triangle A B C has angle measures 68 degrees, 22 degrees, and 90 degrees.
Triangle A B C has angle measures 60 degrees, 30 degrees, and 90 degrees.
Answer:
Step-by-step explanation:
Given that, a series of triangle,
For the sine and cosine to be equal, then,
Sinθ = Cosθ
From, trigonometry identities
Sinθ = Cos(90-θ)
Then,
θ = 90-θ
θ + θ = 90
2θ = 90
θ = 90 / 2
θ = 45°
From the triangle given, using trigonometry ratio,
Sinθ = opposite / hypotenuse.
Sinθ = 20 / 25
Sinθ = 0.8
θ = arcsin(0.8)
θ = 53.13°
The other angles at the triangle is
90-53.13 = 36.87°.

A student has a one-dollar bill, a five-dollar bill, and a ten-dollar bill in a box. The student selects a bill from the box 45 times and selects the ten dash dollar bill 28 times. What formula should be used to calculate the experimental probability? What is the experimental probability of selecting the ten dash dollar bill? What is the theoretical probability of selecting the ten dash dollar bill?
Answer:
r / n
62.2%
33.3%
Step-by-step explanation:
The formula to be used is to divide the number of times that it came out by the total number of times the event was repeated because this was the experiment that was carried out, therefore this would be the experimental formula:
r / n
r = specific event (that the 10 dollar bill comes out)
n = total events
To calculate, we know the previous values r = 28 and n = 45, we replace:
28/45 = 0.622
that is, 62.2% is the experimental probability.
To calculate the theoretical propagation, we know that there are 3 types of banknotes and we want 1 of those 3 types to appear, therefore:
1/3 = 0.333
Ie 33.3% is the theoretical probability

The Cholula Pyramid in Mexico has a height approximately ퟐퟏퟕfeet and a base approximately ퟏퟒퟕퟔfeet by ퟏퟒퟕퟔfeet. The Cheops Pyramid (part of the Great Pyramids) is taller with an approximate height of ퟒퟖퟎfeet but with a ퟕퟓퟓfeet by ퟕퟓퟓfeet base. Determine which pyramid has the most volume
Answer:
The Cholula Pyramid has a bigger volume out of the two.
Step-by-step explanation:
The volume of a Pyramid is V=1/3Bh
Volume of the Choulula = 1/3 (2,178,576)(217)= 157,583,664
Volume of The Cheops Pyramid = 1/3 (570,025)(480)=91,204,000
157,583,664 is greater than 91,204,000
To determine the pyramid with the most volume using the formula for the volume of a pyramid.
The volume of a pyramid: To determine which pyramid has the most volume, we use the formula for the volume of a pyramid: Volume = (1/3) × base area × height.
Cholula Pyramid: Volume = (1/3) × 1456 × 121 = 7307680 cubic feet
Cheops Pyramid: Volume = (1/3) × [tex](585)^2[/tex] × 464 = 47640550 cubic feet
Therefore, the Cheops Pyramid has the most volume.

A baseball coach graphs some data and finds the line of best fit. The equation for the line of best fit is y=0.32x-20.51,where x is the number of times a bat and y is the number of hits.
How many hits should he expect from a player who is at bat 175 times?
We have been given that a baseball coach graphs some data and finds the line of best fit. The equation for the line of best fit is [tex]y=0.32x-20.51[/tex],where x is the number of times at bat and y is the number of hits.
To find the number of hits in 175 times at bats, we will substitute [tex]x=175[/tex] in our given equation as:
[tex]y=0.32(175)-20.51[/tex]
[tex]y=56-20.51[/tex]
[tex]y=35.49[/tex]
Upon rounding to nearest whole number, we will get:
[tex]y\approx 35[/tex]
Therefore, the coach would expect 35 hits from a player who is at bat 175 times.
The expected number of hits = 35.
The given line of best fit is [tex]y=0.32x-20.51.[/tex]
Given that:
x = the number of times a bat = 175.
We have to find y = ?
We plug x = 175 in the given equation.
[tex]y=0.32x-20.51\\y=0.32(175)-20.51\\y=35.49[/tex]
The integer before 35.49 is 35. [Because, number of hits can not be fraction.]
So the expected number of hits = 35.

Answer:
155.9 = h
Step-by-step explanation:
Since it is an equilateral triangle, the angles are all 60 degrees
Call the angle on the bottom right theta
Theta = 60 degrees
The angle h makes with the base is 90 degrees so it is a right triangle
sin theta = opp/ hyp
sin 60 = h/ 180
Multiply each side by 180
180 sin 60 = h
155.8845727 = h
To the nearest tenth
155.9 = h

One coastal cholla cactus can house the nest of the cactus wren containing two adults and up to five young. Six cholla cacti are counted in a study area. What is the maximum number of wrens that could nest in the area?
Answer:
The maximum number of wren that could nest in the area based on the number of cholla cacti is:
42 wrens.Step-by-step explanation:
The information provided by the text mentions that each cholla cactus can house a nest in which two adults and a maximum of five young will live (seven in total per nest), so this information can be represented as follows:
Maximum number of wrens = number of cholla cactus * 7Since six cholla cacti are counted in the area, this value is replaced in the created equation:
Maximum number of wrens = 6 * 7 Maximum number of wrens = 42The area could house a maximum of 42 wrens, where 12 would be adults and 30 would be young at most.

Gavin mixes the amount of red from one shade of paint with the amount of yellow from a different shade of paint. He mixes the batch so he will have the greatest possible amount of paint. What amounts of red and yellow from which shades are used in the mixture?
Answer:It would be 3 1/4 from sunrise, yellow and 5 5/6 red from mango.
Gavin should mix equal amounts of the primary colors red and yellow to achieve the greatest possible amount of orange paint through subtractive color mixing.
Explanation:Gavin is looking to mix paint to create the greatest possible amount of a new paint color. To do this, he should use the primary colors red and yellow to make the secondary color orange. When mixing paints, which is a form of subtractive color mixing, combining these two pigments will result in a new hue without diminishing the amount of paint he has.
In subtractive color mixing, the secondary color orange is created by mixing the primary colors red and yellow in equal proportions. To obtain the largest amount of new paint, Gavin should mix equal parts of the red and yellow shades, assuming that the volumes of paints being mixed are also equal. Thereby, making use of the entire quantity of red and yellow paint to create the largest possible amount of orange paint.
It's important to note that this approach is different from additive color mixing, which involves light colors and operates under a different set of rules. In Gavin's scenario with pigments, red and yellow are the primary colors he should focus on to achieve the desired outcome.

What is the LCM of 30 and 35?
Answer: 210
Explanation: To find the least common multiple for the integers 30 and 35, we start by making a factor tree for each of our integers.
So 30 is 10 · 3 and 10 is 5 · 2.
35 is 7 · 5.
Notice that our 5's match up as factors of each of our integers.
When finding the least common multiple, we simply multiply all of our factors together but since the 5's match up,
we only multiply by a 5 once.
So our least common multiple or LCM is
5 · the 2 that doesn't match up · the 3 that
doesn't match up · the 7 that doesn't match up.
So we have 5 · 2 · 3 · 7 or 210.
